Answer:
Bohr's model of the atom
Explanation:
This model of the atom was proposed by Niels Bohr in 1915.
In this model, the atom has a nucleus containing protons (positively charged) of very small size; the electrons (negatively charged) orbit around the nucleus.
However, unlikely Rutherford's model of the atom, in Bohr's model the electrons cannot have any energy/orbit. In fact, their energies are quantized: this means that the electrons can only be located at specific orbits that corresponds to specific energy levels, and they cannot be found between two orbits.
This model allows to explain the discrete spectra observed in the absorption/emission of light from gases. In fact:
- When an electron jumps from a higher energy level to a lower energy level, it releases a photon whose energy is exactly equal to the difference in energy between the two levels
- When an electron jumps from a lower energy level to a higher energy level, it absorbs a photon whose energy is exactly equal to the difference in energy between the two levels
So, the light absorbed/emitted by a gas can only have some specific (discrete) wavelengths, that correspond to the energy absorbed/emitted by the electrons in the orbit.
Answer:
(I'm pretty sure) Planet A has bigger velocity than Planet B
Explanation:
I'm guessing this is what your question was about:)
Answer:
y = 2.2t + 30.2
Explanation:
t = 3 represents 1983, and t = 9 represents 1989.
Two points on the line are (3, 36.8) and (9, 50).
First, find the slope of the line.
m = (50 − 36.8) / (9 − 3)
m = 2.2
Now use point-slope form to write the equation:
y − 36.8 = 2.2 (t − 3)
If you wish, simplify to slope-intercept form:
y − 36.8 = 2.2t − 6.6
y = 2.2t + 30.2
The number of years that will pass before the radius of the Moon's orbit increases by 3.6 x 10^6 m will be 90000000 years.
<h3>How to compute the value?</h3>
From the information given, the orbit of the moon is increasing in radius at approximately 4.0cm/yr.
Therefore, we will convey the centimeters to meter. This will be 4cm will be:
= 4/100 = 0.04m/yr.
Time = Distance / Speed
Time = 3.6 x 10^6/0.04
Time = 90000000 years.

Complete question:
Tidal friction is slowing the rotation of the Earth. As a result, the orbit of the moon is increasing in radius at approximately 4.0cm/y. Assuming this rate to be constant how many years will pass before the radius of the Moon's orbit increases by 3.6 x 10^6
